Background technology
The core of fiber manufacturing is preform manufacturing technology.At present, common optical fiber processing method mainly has deposition
Method（Chemical vapor, manages outer vapour phase, plasma vapor etc.）And Mechanical Method.Technique at this stage is first to manufacture prefabricated rod mandrel,
Then surrounding layer is manufactured using different technologies in mandrel outer.Compared with sedimentation, Mechanical Method up-front investment is few, it is adaptable to special light
Fine batch machining.The main implementing procedure of Mechanical Method is original fiber glass preparation, and prefabricated rods blank is processed, inside and outside prefabricated rods
The process such as surface grinding polishing and prefabricated stick drawn wire.
The surface quality of preform and optical fiber quality are closely related.In order to obtain the surfaces externally and internally of minute surface level, subsequently
Polishing shaping processing method and technology turn into essential important process；The endoporus of current prefabricated rods and cylindrical polishing master
To be completed by manual operations and mechanical polishing, not only polishing efficiency is low, and labor intensity is big, and be difficult to obtain stable shape face essence
Degree and polishing quality.Therefore, research is directed to the efficient of inner holes of ceramic tubes polishing, great surface quality batch polishing method and device,
Have great importance for the manufacture efficiency and quality for improving preform or even optical fiber.
Common polishing method mainly has chemical polishing, magnetic force polishing, flame polish and polishing etc. of floating.It is limited to optical fiber
The mechanical attributes of prefabricated rods（Fragility is big, and surface is easily scratched etc.）, shape（The inside and outside face of cylinder）, size（Length：150mm, diameter：
20mm, internal diameter are：3-8mm）And equipment investment etc. so that there is larger limitation in the selection of polishing method.
Technique of Magnetorheological Finishing is mainly polished using rheological behavior of the magnetic flow liquid in magnetic field, i.e., in high-intensity magnetic field
Under, the magnetic components of magnetic rheological liquid by theomorphism, can show the property of similar solid and be formed with viscoplasticity
Flexible grinding wheel feature, when magnetic field disappears, it recovers its flow behavior again.The realization of the technology needs piece surface and magnetic current
There is relative motion between change polishing fluid, after addition magnetic field, shearing force can be formed between polishing fluid and piece surface, part is realized
The high quality polished on surface.During MRF, the size for the shearing force that polishing efficiency is depended primarily between contact surface,
Specially magnetic field intensity, many factors such as speed of related movement are determined.
It facts have proved：Magnetic converting technique has excellent grinding-polishing performance.Patent ZL96198445.7 discloses magnetic current
The method of fluid Precision Machining piece surface, in magnetic field, the magnetic flow liquid after being magnetized enters work by flexible polishing wheel
The gap of part and flexible polishing wheel, contacts with workpiece portion surface and throws except the workpiece material contacted.Patent
ZL03124557.9 discloses a kind of sprayable magnetic flow liquid and forms it into the peripheral hardware magnetic field device of jet, and the device passes through control
The position of the size of nozzle surrounding magnetic field processed, direction and workpiece controls the denaturation of magnetic flow liquid, realizes the polishing of workpiece.Patent
ZL200410044076.0 discloses a kind of rotary tool head of ultrasonic-magnetorheological compound finishing device, is passed through magnetic current inside it
Become liquid, under the influence of a magnetic field, tool heads movement locus is controlled by precise control system and then high-precision optics table is formed
Face.
